Yesterday I picked up a copy of The Yahoo! style guide. I’d already looked at some of the content via the website, but it’s great to have the actual book. The guide covers everything from writing mobile-friendly content to copyediting and substantive editing. So far I’ve only read the first section, which gives advice on writing for an online audience (also relevant to other types of writing). I like the way the guide is written; the style is clear and refreshing, and there are plenty of practical examples, tips and exercises.
